12 inch Square Wedding Cake

Asked on 23 May 2016 by Helena Roberts

Delia's Classic Christmas cake recipe.
I've made this cake many times in various sizes, all very successfully, however, I've now been asked to make a 12" square wedding cake, which I have never made. Your recipe conversion chart only goes up to 10". As it is such an important cake can you upscale the ingredients for me or tell me the percentage increase I need from Delia's original recipe in her Christmas book.
Thank you in advance :)

Hello Helena,

I suggest, but have not tested, a 12 egg quantity for your 12 inch square tin. I.e. based on Delia’s chart, add the quantities of the 8 egg to the 4 egg recipe. Then give it extra layers of protection around the outside and make sure the top is covered with a double layer of parchment (not touching the cake mix).

I would check the cake at 5 ½ hours then every 15 – 30 minutes after that depending on how it’s looking.

Although I haven’t tested this version, I have recommended it so many times I feel it must work well, as I have not been told otherwise.

Best wishes

Lindsey
